This invention relates to packaged articles, and more particularly to the packaging and dispensing oi articles in stick form.

In handling articles in stick form, and particularly articles composed of plastic solids, such as crayons, lubricant, cosmetics, etc., it has been common practice to` package such articles in rigid permanent containers from which they are dispensed by moving the article in the container until one end is exposed, or by wrapping the article in paper, thin metal, foil, 0r the like, which can be stripped from the stick to expose successive portions as the stick is consumed.

The rst 0f these methods is extremely eX- pensive and is unsatisfactory because it is impossible to see hcw much oi the unconsumed stick remains, and special means must be provided to advance the stick in its container. The second method does not provide a good support for the stick material and no practical method has been devised to control the length of stick being exposed; usually also a knife or other sharp instrument is required to strip the wrapper from the stick.

It is one of the objects of the present invention to provide a packaged article in the form of stick material enclosed by a relatively thin integral casing, which can be severed from the article in the form 0i a relatively narrow spiral strip. It is a further object of the invention to provide means by which the length cf stick exposed can be accurately controlled at all times.

According to one feature of the invention a collar is provided carrying a small blade which severs the casing from the material as the cellar is turned about the encased stick.

Another object ci the invention is to provide a packaged article or" the type referred to, in which the end of the casing is closed by a cap, which when replaced upon the stick automatically severs so much of the casing as to expose a predetermined length of the stick when the cap is again removed.

Still another object of the invention is to provide a packaged article of the type referred to,

in which the casing is out from the stick material in the form of a narrow spirally extending strip.

The above and other objects, advantages and desirable features of the invention will be apparent from the following description when read in connection with the accompanying drawing, in which:

Figure l is a side elevation of a packaged article embodying the invention;

Fig. 2 is a perspective View of the cap of Figure l;

'Ehe inv ntion is particularly advantageous for the packe. g and dispensing of waXlike materials such as stick lubricants, lip stick, eyebrow pencils, crayons, soaps, and similar solids which are most conveniently employed in stick form. Such articles maybe enclosed in a relatively thin casina formed of metal, foil, paper, plastic lacquers, or like materials which can be cut. One method ci inserting the, stick article in la casing ci tl s type is more particularly disclosed and .in my ctx-pending application, Serial No. 5,752, filed November l5, .194(3, although other methode can be used if desired.

hewn in Figs. l to 4, the article comprises ifi waxlike material enclosed in a tting casing i2, which is relatively thin. g may be an Open tube or may be closed .rd permanently and is adapted to have the op end at which the stick is being used Jsed to cover the stick iii by means ci a cap 4l. The includes a collar portion i5, formed ent its lower end with a screw thread 48, or otherwise formed therein and knurled portions il and ill to facilitate its rotalon, and is closed at its upper end by an end closure portion 2li. The cap is adapted to be placed over the end of the casing and advanced by' turning it so that the screw thread i8 will press a complementary thread in the side wall of the casing and in the stick indicated at in Fig. 3. This is readily accomplished with plastic solid aterials, similar to those enumer *ed within metal, fail, cr similar matei which can readily :be deformed by the *bread it in. the Especially suitable mate ls are r"nuin foil, or foils comp i mix` tures of aluminum, lead and zinc, or for uses where lead is `not permissible, zinc or aluminum alone. Other familiar alloys used for the manufacture of tubes of this character may be employed, vas well as many of the plastic lacquers which remain relatively soft when dry.

Where the material of which the stick is composed is too hard to permit pressing a thread into it, the casing above will receive the thread impression and serve to advance the cap as it is rotated about the encased stick.

The invention contemplates that the cap IB will be provided with a short blade member projecting from the inner wall of the cap to a sufficient depth to cut through the casing i2 as the cap i4 is rotated. In the embodiment of the invention shown in the accompanying drawing, the collar portion i6 of the cap lll is cut adjacent the lower end thereof t form the thin blade member 26, which is pressed inwardly to form the opening 2li. The blade member remains attached to the collar at its lower edge, and extends upwardly and inwardly therefrom at an acute angle to a depth sufficient to penetrate the casing i2 and of a depth suiiicient to sever a strip of the casing of approximately the width of the thread I8, so stick, the casing will be cut vances along the stick.

As the collar is applied to the stick, and rotated to bring the top of the cap snugly against away as the cap adthe end of the stick, the blade 2t will cut into the upper end of the casing and sever it in the form of a relatively narrow spirally extending strip. Due to the angle of the blade, it will at the same time force the strip out through the opening 24, as shown in Figs. 1 and 4, so that the protruding end of the strip may readily be torn off. The collar may be screwed on until the end closure 2G thereof engages the top of the stick, the distance between the blade 26 and the end closure determining the amount of the stick which will be exposed upon subsequent removal of the cap. Thus at no time is the newly exposed portion of the stick exposed until the cap is removed for use of the stick.

Figs. and 6 illustrate an alternative construction which is similar in many respects to the construction of Figs. 1 to 4, and in which the corresponding parts are indicated by the same reference numerals. In this construction, an :annular collar 28 formed with knurled bands 29 is adapted to be rotated about the casing i2 to form the threads upon the body of the casing in much the same manner as the cap M of Fig. 1 operates. The collar is formed with a blade portion 32, which may be formed by slitting the upper edge of the collar axially and bending in a portion thereof at one side of the slit to provide a blade along an acute .angle to the collar. As the collar is turned down over the casing l2 the blade 32 will cut the casing from the stick i0 in the form of a narrow spirally extending strip, and will at the same time guide the strip away from the stick so that it may be torn off easily to expose any desired amount of stick. While the upper end of the collar is open in this construction to leave the end of the stick exposed, a cap 34, as shown in Fig. 9, may be provided to slip over the upper end of the stick and to t essentially over either merely the exposed end of the stick or both the exposed end of the stick and the collar to enclose the stick.

Fig. 7 illustrates a modification of the construction of Fig. 5 and parts therein corresponding to like parts in Fig. 5 have been given the same reference numerals.

that as the cap is rotated upon the a screw thread 39 and In this construction,

the casing itself is preformed with a screw thread 36, complementary to the thread 3G of collar 28, so that the collar may be rotated about the casing and advanced longitudinally without the necessity of forming a thread by the rotation of the cap. This alternative form is particularly suitable where the character of `either the encased stick or the casing material employed does not .readily lend itself to deformation by the cap thread. As the collar is rotated about the threaded casing the blade 32 on the collar cuts the casing away from the stick in the same manner as in the construction shown in Fig. 5.

Fig. 8 illustrates another form of collar which may be used in place of the collars of Figs. 5, 6 and '7, or of the cap of Figure 1. As shown, this collar comprises an annular sleeve 33, knurled with the knurling 39. The blade i9 in this device is formed so that it will, as the collar is turned, make a helical out in the casing and thus advance the collar axially of the casing simultaneously cutting the casing into strip form and forcing the strip outside of the collar. rfhis form of collar differs principally from the other constructions shown in the elimination of the threaded portion of the collar body.
